Description
M/A-COM’s AT-242 is a 3 bit, 4 dB step GaAs MMIC digital
attenuator in a low cost SOIC 8-lead surface mount plastic
package. The AT-242 is ideally suited for use where high
accuracy, very low power consumption and low intermodula-
tion products are required. Typical applications include radio,
cellular, wireless LANs, GPS equipment and automatic gain/
level control circuits.
The AT-242 is fabricated with a GaAs MMIC using a mature
1-micron process. The process features full chip passivation for
increased performance and reliability.
